Simd ghc and llvm Re: PSA: GHC can now be built with Clang

Which reminds me: should we look into getting a patch into llvm'd ghc calling convention so that on avx2 capable machines so we can eventually add support for the 256bit Ymm resisters and primops to ghc? We really should make sure it's patched in on the llvm side first. I believe it'd be a 2 line patch, might even be something we could get into the next llvm point release if there's a clear agreement about it too. Thoughts? I'm happy to put a ticket on trac for this andor do the leg work to make it happen if everyone agrees. On Tuesday, July 2, 2013, Ryan Newton wrote:

Gosh, sorry, yes it's not obvious from the list of accepted papers:

"Automatic SIMD Vectorization for Haskell" Leaf Petersen, Dominic Orchard and Neal Glew One of the authors has a link for it but it appears there's no preprint up yet: http://www.leafpetersen.com/leaf/publications.htm

Err, GCC replacement. But, ironically, GHC [backend] replacement as well, as of the recent ICFP paper.

Got a link or reference?
